Example /api/param?encode(1).framesize=qvga
Example of response encode(1).framesize&202 Accepted(encode(1).status=save)
Interpretation Change JPEG frame size. Specify "vga" or "qvga". File size setting is changed automatically when frame size is changed. If frame size is changed from vga to qvga, file size is changed to third part of original size. If frame size is changed from qvga to vga, file size is changed to three times size.
When frame size of JPEG and
The change is saved by the API, encode(1).status=save. If the change is not saved, the setting is restored by reboot. Allowed users admin, operator
Getting JPEG Rate Control Setting from VN-V686
Format /api/param?encode(1).cbr_mode
Example of response encode(1).cbr_mode=afs&200 OK
Interpretation Acquire the rate control setting of JPEG. Quantization table is fixed in the case of vfs (VariableFileSize). In the case of afs (AverageFileSize), bit rates are controlled such that the average size of multiple files remains constant.

Setting JPEG Rate Control for VN-V686
Format /api/param?encode(1).cbr_mode=data
Example /api/param?encode(1).cbr_mode=vfs
Example of response encode(1).cbr_mode&202 Accepted(encode(1).status=save)
Interpretation Change rate control of JPEG. Rate control can be set to vfs or afs. In vfs (VariableFileSize), quantization table is fixed. In afs (AverageFileSize), average file size of multiple JPEGs is controlled to be constant. The change is saved by the API, encode(1).status=save. If the change is not saved, the setting is restored by reboot. Allowed users admin, operator
Getting JPEG File Size Setting from VN-V686
Format /api/param?encode(1).quality
Example of response encode(1).quality=40k&200 OK
Interpretation Acquire the file size setting of JPEG. If the response is 40k for example, the setting is 40KB. Allowed users admin, operator, user
